A large number of officers and the police helicopter are searching for the youngster.

Inspector Darren Lee, from West Midlands Police's Locate team, said: “We urgently need to find this girl to make sure she gets the medical treatment and any other support she needs.

“We have been working through the night to trace her and that work continues this morning.

“We’re in contact with local schools this morning to try to identify the girl.

“While we are using all our resources to try to safeguard her, we really need the public’s help.

“We’re asking people to be vigilant, and would ask parents to check on their own children.

“If anyone has seen her, we need to hear from them as soon as possible.”

Coventry Police also sent an appeal out on Twitter, writing: “We URGENTLY need the public’s help trying to trace a girl who we believe has been injured in Coventry. Did you see her in the War Memorial Park area? Stay vigilant and call 999 if you see her.”

In a post last night the force wrote: “Officers are in the #Earlsdon area after receiving a call from a member of the public at around 8.30pm (30 Nov), they reported seeing a teenage girl in a distressed state with an injury to her arm.”
